TRASSIR TR-D2251WDIR4 (2.8 mm)

5 MP (2592 × 1944) IP-camera is designed taking into account the conditions of year-round and round-the-clock outdoor operation: protection of the case against moisture and dust - IP67, against mechanical influences - IK08, operating temperatures - –40 ° C ... +60 ° C, lightning protection - TVS 4000 V, integrated IR illumination range - 40 m. Video analytical functions are provided: motion detection (software sensor) and people, virtual line crossing detection, area and loitering control, people counting.


  • WDR 120 dB - Reducing the effect of different contrast lighting on image quality.
  • 3D DNR - spatial noise reduction.
  • Defog - increase the contrast to eliminate the effect of fog and smoke.
  • ROI - fixing on the selected area and parallel reducing the resolution in the rest of the frame to optimize the bitrate.
  • BLC - Backlight Compensation.
  • HLC - local light masking.
  • Compression with H.265 +, H.265 and H.264 codecs.
  • Broadcast speed: 5 Mp - 20 fps, 4 Mp and less - 25 fps.
  • Built-in microphone.

The camera supports corridor mode (vertical resolution) and day / night with ICR: in sufficient light, the filter blocks IR rays, optimizing color rendition, and in the dark it is mechanically shifted away from the matrix to increase its sensitivity and the backlight can work. Bitrate - 8 Mbps.


TR-D2251WDIR4 (2.8 mm) is equipped with a 3.6 mm fixed focal length lens, horizontal field of view 78.3 °, vertical field - 58.1 °, aperture F / 1.8. Interfaces: RJ-45 network port, audio output, alarm input, alarm output, microSD card slot up to 128MB. Power supply - DC 12 V, PoE. The maximum power consumption is 8.5 W. Dimensions - 184.67 × 66.50 × 63.05 mm. Weight - 380 g.
